XCM Cookbook #2633

franciscoaguirre · 2023-12-05T19:44:36Z

Context

XCM docs are currently an md book hosted with github pages: https://paritytech.github.io/xcm-docs/.
While that's fine, it's not in line with the work being done in the polkadot-sdk docs.

Main addition

This PR aims to fix that by bringing the docs back to this repo.
This does not have all the information currently present in the mdbook xcm-docs but aims to be a good chunk of it and fully replace it over time.

I also added the sections guides and cookbook which will be very useful for users wanting to get into XCM.
For now I only added one example to the cookbook, but have ideas for guides and more examples.
Having this docs be in rust docs is very useful for the cookbook.

TODO

Use FungibleAdapter
Improve and relocate mock message queue
Fix license issue. Why does docs/sdk/ not have this problem? (Just added the licenses)

Next steps

More examples in the cookbook
End-to-end XCM guide with zombienet testing

The XCM docs were pretty much moved to the new rust docs format in #2633, with the addition of the XCM cookbook, which I plan to add more examples to shortly. These docs were not mentioned in the polkadot-sdk rust docs, this PR just mentions them there, so people can actually find them.
